Vibrationally excited states of CCH radical, up to 5000 cm-1 above the ground vibrational level of the X2X+ state, have been studied by laser-induced fluorescence in both a flow cell and a supersonic beam expansion. CCH radical was generated by photolyzing acetylene with 193 nm laser light. Ten uv bands of parallel type transitions have been assigned as the transitions from X(0, ν2, 0) (ν2=1, 3-11) to S (K=0) or U (K=l). Comparison between the experimental observations and ab initio calculations of the bending vibrational levels will be given.
